Standard Ignition Shift Interlock Actuator P/N:SIA100
Standard Motor Products
Standard Ignition TCA300 shift interlock actuator for the 2011-2018 Ford Focus and other vehicles is designed to restore transmission shifting function. A shift interlock actuator keeps the shifter in park until the brake pedal is pressed.
A shifter that will not leave park with your foot on the brake, or one that moves out of park without the brake, can mean the actuator has failed. A faulty brake light switch, a worn shifter cable or a weak battery can be behind those signs too, so find the cause before you buy a new actuator.
It is a direct-fit replacement for the 2011-2018 Ford Focus and the 2011-2019 Ford Fiesta, designed for ease of installation and to meet or exceed OE performance. This listing is one actuator, and both of these cars take two.
